The rating of this gene has been updated to Green following NHS Genomic Medicine Service approval.Created: 31 Jan 2023, 10:54 a.m. | Last Modified: 31 Jan 2023, 10:54 a.m.
Panel Version: 2.7
Comment on list classification: This panel is relevant in view of the multiple congenital malformations associated with OTUD5 variants and therefore this gene may be promoted to Green at the next major review - at least 8 unrelated families reported with distinct hemizygous variants (PMIDs: 33131077 and 33523931).Created: 10 Feb 2021, 11:28 a.m. | Last Modified: 10 Feb 2021, 11:28 a.m.

OTUD5 is associated with a relevant phenotype in OMIM but not yet in Gene2Phenotype.
- PMID: 33131077 (2021) - 13 male patients from a single family with three generations affected. Patients presented prenatally or during the neonatal period with IUGR, ventriculomegaly, hydrocephalus, hypotonia, congenital heart defects, hypospadias, and severe neurodevelopmental delay. The disease is typically fatal during infancy, mainly due to sepsis (pneumonias). Female carriers are asymptomatic. WGS in four individuals identified a unique candidate variant in the OTUD5 gene (NM_017602.3:c.598G > A, p.Glu200Lys). The variant cosegregated with the disease in 10 tested individuals.
- PMID: 33523931 (2021) - Another 10 individuals from 7 families reported. Key features include poor growth, global developmental delay with impaired intellectual development, and variable abnormalities of the cardiac, skeletal, and genitourinary systems. Most affected individuals also have hypotonia and dysmorphic craniofacial features. Brain imaging typically shows enlarged ventricles and thin corpus callosum; some have microcephaly, whereas others have hydrocephalus. The severity of the disorder is highly variable, ranging from death in early infancy to survival into the second or third decade.
